2017-02-20Ensure prim_eval:'receive' wont clobber def_arg_reg[0]Rickard Green
def_arg_reg[0] is used for storage of timeout instruction when a 'receive after' is executed. When a process was scheduled out inside prim_eval:'receive'/0 due to a function call, def_arg_reg[0] was overwritten due to storage of live registers. prim_eval:'receive'/2 now calls arg_reg_alloc/0 which bumps all reductions and then calls arg_reg_alloc/7 which will cause an allocation of a new arg_reg array since def_arg_reg only can hold 6 values. This ensures that the timeout instruction in def_arg_reg[0] used for the timeout wont be overwritten.

2017-02-17Teach make_preload to handle the new 'AtU8' chunkBjörn Gustavsson
26b59dfe67 introduced the new 'AtU8' chunk to support Unicode atoms. make_preload strips the pre-loaded BEAM files so that they only contain essential chunks. It expects to find the old 'Atom' chunk. Teach make_preload to read the new 'AtU8' chunk instead of the old chunk. Also produce a nice error message if someone by mistake compiles the pre-loaded modules with an OTP 19 compiler.

2017-02-14erts: Add deallocation veto for magic destructorsSverker Eriksson
A magic destructor can return 0 and thereby take control and prolong the lifetime of a magic binary.

1> round(6209607916799025.0). 6209607916799026 Problem: Adding/subtracting 0.5 and large double floats between (1 bsl 52) and (1 bsl 53) does not give reliable results. Solution: Use round() function in math.h.

2017-02-06Implement magic referencesRickard Green
Magic references are *intentionally* indistinguishable from ordinary references for the Erlang software. Magic references do not change the language, and are intended as a pure runtime internal optimization. An ordinary reference is typically used as a key in some table. A magic reference has a direct pointer to a reference counted magic binary. This makes it possible to implement various things without having to do lookups in a table, but instead access the data directly. Besides very fast lookups this can also improve scalability by removing a potentially contended table. A couple of examples of planned future usage of magic references are ETS table identifiers, and BIF timer identifiers. Besides future optimizations using magic references it should also be possible to replace the exposed magic binary cludge with magic references. That is, magic binaries that are exposed as empty binaries to the Erlang software.

2017-02-06Atomic reference count of binaries also in non-SMPRickard Green
NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc()
